If you often have trouble falling asleep quickly, perhaps a change in your shower schedule can help. Taking a warm shower or bath at night adjusts your body temperature so you're nice and groggy by the time you hit the sack.

When you come out of a warm shower into a cooler bedroom, your body temperature will drop. That drop in temperature signals your body that it's time to rest, slowing down essential metabolic functions including heart rate, breathing, and digestion.

Greatist suggests keeping your showers short and moderately warm—between 5 and 15 minutes and under 104°F (normal hot tub temperature)—to avoid raising your body temperature too much and instead making you feel energetic. You can also gradually lower the water temperature at the end of your sleep-inducing shower.
